<UserDocu>Checks if the shape is closed
If the shape is a shell it returns True if it has no free boundaries (edges).
If the shape is a wire it returns True if it has no free ends (vertices).
(Internal and External sub-shepes are ignored in these checks)
If the shape is an edge it returns True if its vertices are the same.
